Answer:
30
Step-by-step explanation:
40- 10 equals 30
the range is the maximum divided by the minimum.
Answer:
B=48, A=106
Step-by-step explanation:
Using A and B as the unknown variables, not the point names.
The lines in the angles of B and D mean that those angles are congruent, or the same. B=D, so B=48. The lines are the same length, as marked with the arrows, which leads to unknown variable A=106, like point A shows.
Answer:
29
Step-by-step explanation:
We can use the formula (a+b)(a-b)=a^2-b^2 to help us simplify this problem.
I hope this helps! Please comment if you have any questions.
Volume=height times area of base
area of base=pi times r^2
volume=(h)(pi)(r^2)
diameter=2r
diameger=8
8=2r
divide 2
4=r
h=3 times r
h=3r
r=4
h=3(4)
h=12
r=4
h=12
pi=3.14
subsitute
volume=(12)(3.14)(4^2)
volume=(12)(3.14)(16)
volume=602.88 in^3
